Hi freinds there is scalpe shampoo claim that there is bestest shampoo for dandruff and many skin doctors also recommended in them priscriptions but for my side I use after this product is not worthy as 100+ bucks is this apply as other normal shampoos. Very first day I use it but as per they claim dandruff will gone in first wash is not really works and as prescibed by doctor I use evry thrice day and use 1 bottle but no visible result I use it more six bottles and as soon as I stop using this dandruff is there again and this time its much than before so final conclusion is that scalpe only wash your visible and upper dandruff not cure it or prevent it and it last only 2-3 days . so I recommended dont waste your money for buying this
